Can we use genetic algorithms to evolve datasets?
This question raises a lot more questions. It seems like a solution looking for a problem, instead of the other way round.

How do you measure the fitness of a feature?
What would one of the &quot;evolved datasets&quot; mean? What does it represent?
What would your overal purpose be? If you just wish to generate simulated datasets, there are easier ways to do this, with more control over the various aspects of the resulting datasets.

If you want to compute a new set of features to &quot;better&quot; describe a given dataset, there are many approaches to this, such as PCA, ISOMAP, self-organizing maps, ... If this is the kind of thing you're thinking about, I would recommend starting there.
